The DelayUntilReboot flag is invalid for this method.

Error message

The DelayUntilReboot flag is invalid for this method.

What it means

An argument validation error inside DirectoryInfo.MoveTo: the code validates the MoveOptions flags and rejects MoveOptions.DelayUntilReboot because a move of an existing directory object cannot be deferred to reboot (that flag only applies to file-copy style APIs). It fires when the caller's moveOptions contain DelayUntilReboot.

Solutions

1. Remove MoveOptions.DelayUntilReboot from the moveOptions argument
2. Perform the move immediately without the deferral flag, retrying later at application level if needed
